Brown Whitespotted Puffer
The Brown Whitespotted Puffer (Arothron meleagris), also known as the Guinea Fowl Puffer, Speckled Puffer, Speckled Balloon Fish, Golden Puffer and Fugu has the ability to inflate by inhaling air or water. This is a protective defense that Puffers have which prevents them from being eaten by other fish. When it expands and inflates itself, a predator finds it difficult to swallow or get its mouth around the fish. When inflated, this Puffer's body has a soft prickly texture, which is harmless... to the touch. The Brown Whitespotted Puffer can grow to 14" in length. It eats a wide variety of marine life, but it feeds mainly on tips of branching corals and to a lesser extent on sponges, mollusks, bryozoans, tunicates, algae, crabs, shrimps, and detritus. In captivity, it may not be quick to adjust to tank fed fares, because of its coral diet preference. However, once adjusted it may accept freshly chopped or frozen fares, such as shrimp, crab, squid and fish, and possibly herbivore fares. Of course, it is not suitable for reef tanks.
